B4J Question File.DirData has red squiggly underline... why?

[cklester]

The IDE is putting a red squiggly underline under this line:

Log(File.DirData)

When looking at the TextFiles.b4j example, it uses the File object just fine.

I can't figure out why the TextFiles example works, but my code does not.

Isn't File a built-in, so I can just up and use it? I did a search for DirData and haven't found the answer.

I have the following checked in the Libraries Manager: B4XPages, jCore, jFX, and jNet.

Log(File.DirData(""))

Have a look at the contextual help and the error message in the Logs Tab.

A parameter (AppName As String) is missing.

Dang. Always trust the contextual help!

I thought I saw an example somewhere where @Erel used exactly what I was trying: Log(File.DirData), so I thought that was gospel. I think I saw this, though, and got confused.

Thank you, @LucaMs and @Jorge M A !

Tip: easier to use XUI.DefaultFolder + XUI.SetDataFolder.
